Product Filter by Attribute and price range on products list

Hello
I have the Product filter by attribute and price range on my site I would like to know if I can add those features on the product list next to the "Filter results by" drop down box that is already there. Or can i remove the existing search by option and replace it with this mod, if so does anyone know what file I would need to edit.

Any help would be appreciated :(
Thanks

Have you tried clicking the heading "Price"???

i mean if i can use this mod as alpha product filter like "Filter Results by" i know i have to add code to "includes/modules/product_listing_alpha_sorter.php and inclubes/index_filters/default_filter.php but i don`t know nothing about about coding can some please help me with this.
Any help would be appreciated
Thanks
